media: vimc: Add support for contiguous DMA buffers

2022-02-16T11:47:02Z

The vimc driver is used for testing purpose, and some test use cases involve sharing buffers with a consumer device. Consumers often require DMA contiguous memory, which vimc doesn't currently support. This leads in the best case to usage of bounce buffers, which is very slow, and in the worst case in a complete failure. Add support for the dma-contig allocator in vimc to support those use cases properly. The allocator is selected through a new "allocator" module parameter, which defaults to vmalloc.

We never use _ in directory names in the media subsystem, so rename to test-drivers instead for consistency. Also update MAINTAINERS with the new path. Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab
